Outcome Measures
Primary Outcome Measures
- IOL rotation degree at one hour [one hour]
After the pupil was dilated, the IOL axis was recorded using the same slit-lamp microscope. IOL rotation was defined as the difference between the target and final axis.
- IOL rotation degree at one day [one day]
After the pupil was dilated, the IOL axis was recorded using the same slit-lamp microscope. IOL rotation was defined as the difference between the target and final axis.
- IOL rotation degree at three days [three days]
After the pupil was dilated, the IOL axis was recorded using the same slit-lamp microscope. IOL rotation was defined as the difference between the target and final axis.
- IOL rotation degree at one week [one week]
After the pupil was dilated, the IOL axis was recorded using the same slit-lamp microscope. IOL rotation was defined as the difference between the target and final axis.
- IOL rotation degree at two weeks [two weeks]
After the pupil was dilated, the IOL axis was recorded using the same slit-lamp microscope. IOL rotation was defined as the difference between the target and final axis.
- IOL rotation degree at one month [one month]
After the pupil was dilated, the IOL axis was recorded using the same slit-lamp microscope. IOL rotation was defined as the difference between the target and final axis.
- IOL rotation degree at three months [three months]
After the pupil was dilated, the IOL axis was recorded using the same slit-lamp microscope. IOL rotation was defined as the difference between the target and final axis.
- IOL rotation degree at six months [six months]
After the pupil was dilated, the IOL axis was recorded using the same slit-lamp microscope. IOL rotation was defined as the difference between the target and final axis.
- IOL rotation degree at one year [one year]
After the pupil was dilated, the IOL axis was recorded using the same slit-lamp microscope. IOL rotation was defined as the difference between the target and final axis.
- IOL rotation degree at three years [three years]
After the pupil was dilated, the IOL axis was recorded using the same slit-lamp microscope. IOL rotation was defined as the difference between the target and final axis.
